The invention belongs to the technical field of data exchange and discloses a cache control method and system, a storage medium, computer equipment and an application. The method comprises the steps:enabling one Block RAM to be controlled into a plurality of three-channel synchronous FIFOs for use, writing data frames into corresponding on-chip FIFOs when the data frames enter a queue, and writing the data into an off-chip DDR after the on-chip FIFOs are fully written; dividing the DDR storage space into L area blocks with continuous addresses; when data dequeues, moving k continuous data frames to the on-chip FIFO from the DDR while the data is read from the corresponding on-chip FIFO. According to the invention, the processing speed and the traffic burst resistance of the packet processing unit are improved, the DDR bandwidth utilization rate is increased, and the time delay of DDR data reading is reduced. According to the invention, the processing speed of the switching unit is accelerated, a relatively high DDR bandwidth utilization rate is realized, and the influence of absolute time delay brought by a DDR device on the processing time of the switching unit is reduced.

The present invention provides an automatic abstracting and filtering method in Chinese-English phrase translation. The method of the invention comprises the following steps: extracting the characteristic information which divides the language block and filters the candidate phrase to original Chinese-English double-language sentence pair; confirming the language block division anchor point according to different characteristic information, dividing the original Chinese-English sentence pair to a plurality of single language blocks; extracting the candidate phrase in the language block with the word aligning information of original Chinese-English double-language sentence pair; and filtering the generated candidate phrase according to the characteristic information of generation frequency of candidate phrase for generating the required phrase pair. The invention adopts the phrase abstraction in the traversing language block and is especially useful for the indefinite expanding of empty word thereby effectively settling the requirement to the storing space caused by the overgreat extraction amount of phrase, and effectively filtering many noise phrase. The invention can generate a plurality groups of phrases directly according to the fixation word alignment of present sentence pair thereby increasing the recalling rate of phrase pair under the precondition of satisfying the precision.

The embodiment of the invention provides an information processing method and apparatus. The embodiment of theinvention abandons a storage structure in the prior art. First, null fields can be avoided, so a problem of null field wasting storage space can be prevented and storage space can be saved; second, each field in the prior art can only store one attribute value, but one attribute storage field can store a plurality of attribute corresponding relationships in theembodiment; each attribute corresponding relationship has an attribute value; and therefore, compared with the prior art, in the embodiment, one attribute storage field can store a plurality of attribute values, so storage space of one attribute storage field can be fully utilized and storage space can be saved.

The invention discloses a log writing method and device, a system and a computer storage medium. The method comprises the steps that an end point page number which is written into a log is read from avariable area of a log disk; the log is written into a data area page corresponding to the end point page number to form a log page; the writing position corresponding to the log page and a data section number which the log page belongs to are acquired and stored into a bitmap area of the log disk; in the variable area of the log disk, one is added to the end point page number which is written into a log, and whether or not the log is written to a tail disk of the log disk is judged; if yes, an end point which is written into the log is set to a disk head.

The invention provides a data transmission system, a data transmitting, transferring and receiving method and an electronic device. The data transmitting method is used for transmitting the data of a first device to a second device. The first device comprises a first capacitive touch control panel, and the second device comprises a second capacitive touch control panel. The data transmitting method comprises the steps of selecting data of the first device to be transmitted by a user, aligning the first capacitive touch control panel with the second capacitive touch panel, transmitting the to-be-transmitted data of the first device to the first capacitive touch control panel, and forming a capacitive coupling between the first capacitive touch control panel and the second capacitive touch panel. The second device obtains the to-be-transmitted data of the first device through the variation of the capacitive coupling between the first capacitive touch control panel and the second capacitive touch panel.

The invention discloses a limestone powder storage bin and relates to the limestone field. The limestone powder storage bin comprises a cylinder and a cone, a pressure vacuum release valve, a manholeand at least one feeding hole are arranged at the top end of the cylinder, a pulse bag type dust collector connected with the feeding hole is arranged above the feeding hole, at least one ultrasonic liquid level meter is arranged at the top end in the cylinder, a probe of an ultrasonic liquid level meter is vertically arranged downwards, a first blowing pipe is arranged below the ultrasonic liquidlevel meter, one end of the first blowing pipe penetrates through the cylinder to be connected with an external air source, the other end of the first blowing pipe is arranged in a closed mode, and afirst blowing branch pipe pointing to the ultrasonic liquid level meter and a second blowing branch pipe arranged vertically downwards are arranged on the first blowing pipe.

A data structure of audio-video disc has a pilot data file, which uses multiple forms of different data classes for respectively recording the information associated with another audio-video data file on the disc. Each form has a head and a serial number. In each data class, there is an edit information form for recording the edited information in this data class. The newly added or edit form is written to disc in additional mode. At the beginning of reproducing audio-video data, all the forms are combined into a pilot data file. As a result, the newly added or edited audio-video data can be reproduced without modifying original pilot data file.
